Research and implement on industry control networks based on embedded SERCOS-III protocol

SERCOS-III is the international standard on the third generation serial communication protocol for real-time data communication among the controller and actuators with the advantage of openness, compatibility, high speed, and reliability. Based on studying on the SERCOS-III protocol and ARM embedded control technology, presents one kind of SERCOS-III high speed communication system and discusses the technical implement details of hardware and software. Furthermore, a reduced TCP/IP protocol is supported in the IP channel so that the configuration parameters and the situation detections of the slaves can be operated through the internal IP channel. The simulation experiments of a network control system are presented to validate the proposed system.
